Stevebayb 0 Posted May 26, 2010 Hello. I was wondering if any body knows what protocol works with a dennard 2050 with a drx100..I amtrying to control the dome with software called ptz cntroller,but on the drop down list it does not state anything for dennard,t does have pelco d etc.i have set the baud rate to 9600 and tried all protocolsbut im not being able to control it....The other question is that i have used the serial port on the pc and connected pins 3 and 5 ,do these two cables become a twisted pair and go to the tp connectins in the drx100 ...Thank you Steve Share this post Link to post Share on other sites
